Abstract

The invention discloses a dynamic gesture recognition method, system, readable storage medium and computer equipment. The method includes: performing hand target detection on a target image through a trained hand detection deep learning model to obtain the smallest hand area The graphic information of the circumscribed rectangle; according to the graphic information of the minimum circumscribed rectangle corresponding to the second moment and the first moment, calculate the center distance and slope between the minimum circumscribed rectangle corresponding to the two moments; through the skin detection algorithm, segment the hand of the target image Combined with the depth map, calculate the average depth of the hand skin area corresponding to the second moment and the first moment respectively; determine the gesture movement direction according to the center distance, slope, and the average depth value of the hand skin area corresponding to the two moments and the amount of motion in the corresponding direction. The invention can solve the problems that the prior art can only determine the moving direction on the two-dimensional plane, the calculation process is complicated, and the real-time performance of gesture recognition is low.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a dynamic gesture recognition method, device, readable storage medium and computer equipment. Background technique [0002] Gesture recognition is an important means of human-computer interaction. In VR (Virtual Reality, virtual reality technology) human-computer interaction, users can adjust the volume or control other virtual mobile buttons through virtual gesture recognition. [0003] In the prior art, the image is mainly gridded, and the skin detection algorithm is used to mark whether there is a hand in each grid, the binarized image, and then the direction of the hand movement is obtained through the logical operation of the binary image. This method can only Determine the direction of movement on a two-dimensional plane. In addition, there is also gesture recognition based on the Tower algorithm. The calculation process is very complicated and the amount of calculation i...
